Democratic presidential candidate Bernie Sanders rallied in San Pedro Friday on the sixth day of his Southland campaign ahead of California's June 7 primary election.

"I tell you it is too late for establishment politics and establishment economics,'' Sanders told the union-dominated crowd of about 1,000 people at the Los Angeles Maritime Museum. "We need a political revolution.''

"A moral economy is not an economy where CEOs make tens of millions of dollars a year, ship our jobs abroad and take away health care from their workers,'' he said. He added later, "Our ideas are the future of this country. Let's stand up. Let's fight for them."

Sanders was also scheduled to be interviewed on the HBO talk show "Real Time with Bill Maher" on Friday.

The 74-year-old Sanders, a self-described democratic socialist who would be the nation's first Jewish president, spoke at a rally Thursday at Ganesha High School in Pomona and appeared on the ABC late-night talk show "Jimmy Kimmel Live.''

Sanders' opponent, former Secretary of State Hillary Clinton, was in Oakland Friday in what her campaign describes as "a community discussion on breaking barriers and increasing opportunity.''

Following last week's Kentucky and Oregon primaries, Sanders holds 1,539 delegates, trailing behind front-runner Hillary Clinton, who is only 78 delegates short of the 2,383 needed to win the nomination.
